Editing Knoppix (section)

== Boot options ==
When using Knoppix as a Live CD, one can use boot options, also known as "cheatcodes", to override a default setting or automatic hardware detection when it fails. For example, the user may wish to boot into a plain console, or proceed without SCSI support. For this, Knoppix allows the user to enter one or more cheat codes at the prompt before booting. If the user does not enter a cheat code, or does not press any key before the timeout, Knoppix will boot with its default options. For example, to set the language to French rather than the default, one would type:

<code>knoppix lang=fr</code><ref name="Cheat codes"/>

Knoppix is a [[32-bit]] [[Debian]] Linux based distro, but recent releases (including the latest version 7.6) have also been equipped with a [[64-bit computing|64-bit]] kernel on the DVD edition, where it will automatically boot up for 64-bit computers, or by using the boot option <code>knoppix64</code> manually in the command-line prompt, while <code>knoppix</code> will boot up the 32-bit kernel. Neither PAE nor 64-bit applications are supported by Knoppix, and more than 4GB of system memory can only be used with a 64-bit kernel.

The DVD edition of Knoppix can also be loaded onto a USB flash drive, with ''flash-knoppix'' under the Knoppix system, such that "the KNOPPIX Live System starts and runs about factor 5 faster from USB flash disk than from CD or DVD!".<ref>{{cite web|url=http://knopper.net/knoppix/knoppix760-en.html|title=KNOPPIX 7.6.0 / ADRIANE 1.7 - Live DVD|last=|website=knopper.net|access-date=4 May 2018|url-status=live|archive-url=https://web.archive.org/web/20171004003927/http://www.knopper.net/knoppix/knoppix760-en.html|archive-date=4 October 2017}}</ref> Besides that, the experimental [[UEFI]] support is provided for USB flash drive rather than DVD media. 32-bit UEFI firmware can only boot up the 32-bit kernel, while 64-bit UEFI firmware can only boot up the 64-bit kernel. The text interface for UEFI is similar with it for BIOS, one can also press key F2 and F3 to access information on boot options.
